Final answer:
The comparison highlights the realization of the importance of living space adequacy over utility structures, with sheds representing a larger presence compared to the modest house.
Step-by-step explanation:
The comparison between the sheds and lean-tos and the modest house suggests that Paul and Rex had a realization about the disparity in size and perhaps function of the different structures on the property. The sheds and lean-tos, presumably larger and more numerous, overshadow the small and seemingly inadequate house. This reflects a moment of revelation where the importance of comfort and functionality of living spaces is recognized over the mere utility of agricultural buildings.
